Question

Write a single rule that combines these two translations
(x, y) to (x - 7, y)
(x, y) to (x + 14, y + 10)

Answer 1

what did you get

Answer 2

notice in the first rule how x turns into x-7

this means you move 7 units to the left on the x axis

now x to x+14 means you move 14 units to the right on the x-axis


Combine the two rules: start at some point, move 7 units to the left, then move 14 units to the right

what's a simpler way of saying all this?

Answer 3

(x, y) too (x + 7, y )

Answer 4

good, you got the x coordinate part correct

Answer 5

now you just have to figure out the y coordinate

Answer 6

wouldn't it be 10?

Answer 7

not just 10, but what else

Answer 8

10y

Answer 9

not 10y but you're getting closer

Answer 10

ohhhhh, y + 10 ?

Answer 11

you got it

Answer 12

so the combine rules give you this new rule

(x,y) --> (x+7, y+10)
